That doesn't quite sense to me, unless I really don't understand the concepts here. Unreal didn't cut anything from your game though...? Meaning, I downloaded your 700MB or so zip, but when i unzipped it, it ballooned to 6GB on my hard drive. So... it was there already compressed in the zip file, no? Or do you mean somehow Unreal created the extra 5.3GB there on the spot?!
